We introduce a new mechanism and control system for wireless assistive finger training. The proposed mechanism and control system can provide natural finger flexion and extension via magnetic force and torque between a driving coil and a multi-link magnetic assist device placed on the fingers. The proposed mechanism is designed to allow normal movement while maintaining a natural finger shape, even when multiple magnets are applied to the fingers. Anatomical features were considered in the design to accommodate the angular changes between the fingers during hand extension and flexion. The magnetic force between the control system and the device on the hand allows extension and flexion of the fingers without the use of wires and electrical motors. The performance of the driving system and the magnetic device were verified through various simulations and experiments. A control program with motion tracking is also developed using LabView software. Hence, a wireless assistive finger training system is successfully realized.

Greenhouse environment system is an often nonlinear, change and inertia complex system. It is very hard to build math model and control. Since moisture and temperature have a influence to crops grow, we select them to build the manner of control system, applying fuzzy control system to design moisture and temperature controller, and to write fuzzy control program based PLC, then we should observe the factual control effect. The result of system running show: when temperature is set to 25oC and moisture is 80%RH, the process of control is stable and the system is very stable, it can meet the greenhouse requirement.

Thermoelastic martensitic phase transition in Ni-Ti based shape memory alloys enables designing micro- and nanotools that are controlled by small changes in temperature (~10°С). This makes it feasible creating a new generation of complex microrobotical systems for manipulation and treatment of various nanoobjects in nanoindustry, medicine, nanoelectronics, etc. This work deals with the development of a physical and mathematical model for the micro manipulation system. The system under investigation pertains to shape memory composite nanotweezers with the composition Ti2NiCu/Pt located at the tip of a tungsten microneedle. The activation and control of the nanotweezers is done by heating them by the passage of an electric current flowing through a microdiode located in the needle. The microdiode serves the twin purpose of Joule heating and temperature sensing/measurement so as to close the feedback loop of the control system. The prototype of the control system was manufactured and tested. The data from the simulation were compared with those from the preliminary experiments.
